Best Open Source Accounting Software: Reviews and Comparison

By Nguyen OanhUpdated: July 27, 2022, first publication: May 2022

Accounting is an important part of every business but sometimes it is also the most difficult. This is where open source accounting software comes in, as a solution that can save the day!

If you are looking for open source accounting software to handle all of your bookkeeping and accounting activities, Appvizer will show you point by point what an open source accounting software is, its benefits, its features, and we’ll even give a comparison of open source accounting software for your business.

Let's get into it now!

What is Open Source Accounting Software?

Let's go over a little reminder: The term "open source" means that the source code of the software is public and accessible. The software in question can then be modified and distributed by any individual

The utility provided by open source accounting software is threefold: ease, efficiency, and autonomy.

  • Ease, because you no longer have to multiply calculations or switch from one file to another to cross-check your accounts, synthesize them, and have a global view of the state of your company and its activity.
  • Efficiency, because open source accounting software saves you a lot of time, and therefore money. In addition to saving you money, they adapt perfectly to your expectations, which is the hallmark of open source.
  • Autonomy, because in a sense, open source accounting software does not require you to spend extra money, hiring a chartered accountant, for example, would cost you several thousand dollars per year. These programs are often free and require at most one download from the web.

Benefits of Open Source Accounting Software

Open source software has several advantages: 

  • First of all, they are freely available, and no license is required (often at the expense of a not very modern design). 
  • By using open source software, you also benefit from greater independence, unlike paid software. 
  • Finally, they are very flexible. You can also tailor-make your open source accounting software.

When unqualified employees use software they’re not trained in, it can waste time and sometimes lead to errors. In order to resolve this, companies sell services based on these free open source accounting software: they program them according to particular business needs, install them on-premise, and provide maintenance and support.

Limitations to Open Source Accounting Software

As for the limitations, open source software generally does not include assistance or support when learning how to use the software. Apart from forums to exchange with other users, you have to manage them on your own, and therefore master the necessary techniques to work on these kinds of tools. They also can benefit from rather innovative evolutions but this can take time to come about. 

The Key Difference: Open Source Software vs. Free Software

The difference between free software and open source software is not easy to distinguish. It lies in their values and in their vision.

Open source

An open source software is "open" in the sense that everyone has the possibility to access its source code. In addition to this, it is possible to redistribute the source code and create derived software products.

The Open Source Initiative (an organization founded in 1998 by Bruce Perens and Eric Raymond) focuses on technical aspects. It is compatible with the coexistence of software whose code is open but not free.

However, these days a significant part of open source software is also free.

Free software

The free software movement goes further and advocates for certain philosophical. 

Described for the first time in the 1980s by Richard Stallman, and popularized by his very strong campaigns (with very strong opinions) via the FSF or Free Software Foundation, the formal definition of Free Software is based on four freedoms:

  • Freedom to run the program, for any purpose.
  • Freedom to study the operation of the program and to adapt it to one's needs.
  • Freedom to redistribute copies (underlying principle: help others).
  • Freedom to improve the program and publish those improvements (to benefit the whole community).

Two of these freedoms, the freedom to study how a program works and the freedom to improve it, imply access to the source code and thus that the software is open source.

The Features of Open Source Accounting Software

There are lots of open source accounting software programs on the market but they always have some features in common such as

  • Customers/suppliers: managing invoices, credit notes, receipts, payments, and the list of all your customers or suppliers
  • Bank and cash: recording bank statements, cash receipts, and payments
  • Accounting documents: accounting entries, accounting documents, supporting journal
  • Chart of accounts: chart of accounts and tax plan
  • Periodic tasks: all drafts not yet validated and recorded in accounting entries
  • Reports: general ledger, balance sheets, journals, and taxes

But, what is the best open source accounting software program? Which criteria should you consider while choosing the best system? Keep reading, we'll answer it in the next part.
